“Study: Melting sea ice major cause of warming in Arctic“. Anthony Watts tries to distract from a Nature climate paper [update: PDF here.] by muttering about transient temperature recording errors that never actually enter the climate data.
Dr. James Screen of the University of Melbourne reports that Arctic climate change is driven more by declining sea ice than by warmer air circulating up from lower latitudes.
Does this explain the model/observation gaps discussed in Stroeve, et al 2007?
